Abstract

The invention provides a universal curved-surface clamp which comprises an upper clamping part and a lower clamping part, wherein a lifting part is arranged between the upper clamping part and the lower clamping part and is used for adjusting the distance between the upper clamping part and the lower clamping part, and a workpiece to be processed is arranged between the upper clamping part and thelower clamping part; a plurality of clamping bars are arranged on the upper clamping part and the lower clamping part, and the clamping bars of the upper clamping part correspond to the clamping barsof the lower clamping part; the clamping bars are correspondingly provided with elastic components; and a clamping curved surface corresponding to the workpiece to be processed is formed between theclamping bars of the upper clamping part and the lower clamping part, through the elastic components. The spring stiffness of the universal curved-surface clamp is moderate, the pretightening force issmall and does not damage the workpiece, and the flexible clamping is realized.

Description

technical field [0001] The invention belongs to the technical field of automobile parts processing, and in particular relates to a universal curved surface fixture. Background technique [0002] In the field of automobiles, whether it is the exterior sheet metal shape or the interior parts, the automobile structure mostly appears in the form of curved surfaces. fixtures. With the introduction of new models and rapid replacement in the automotive field, if special fixtures are made for various curved surfaces of different structures, although the fixtures are directly processed in place, the reserved space is small, and the precision is high, the special fixtures have poor versatility and are not conducive to mass production. Or unified purchase and inventory storage, resulting in high production and management costs, low utilization rate, and serious waste of materials and production capacity. Contents of the invention [0003] In view of this, the present invention aims...
